Abstract

The method comprises the steps of measuring the offset of reception TM by a moving station of synchronisation signals originating from a first and from a second fixed station, measuring the times of propagation t1, t2 of a synchronisation signal between the fixed stations and the moving station, and calculating the offset of transmission TR between the synchronisation signals according to the relationship TR = TM + t1 - t2. <IMAGE>
